摘要: 讨论在非凸非精确线搜索时,Broyden算法的的收敛性. 证明当Broyden算法得到的点列收敛时, 该点列一定趋向于稳定点.

关键词: Broyden算法, 收敛性, 凸性, 精确线搜索

Abstract: In this paper we discuss the convergence of the  Broyden algorithms without convexity and exact line search assumptions. We prove that if  the algorithm produces a convergence point sequence, then the limit point of the sequence is  a critical point of the objective function.

Key words: Broyden algorithms, convergence, convexity, exact line search
